A number of irradiation methods were applied for various durations in field studies to examine the efficiency of removing HCHO, TVOC, bacteria, and fungi. The removal efficiency of air pollutants (HCHO and bacteria) through long-term exposure to UVGI appears to increase with time. The effects on TVOC and fungi concentration were insignificant in the first week; however, improvements were observed in the second week. No differences were observed regarding the removal of HCHO and TVOC among the various irradiation methods in this study; however significant differences were observed in the removal of bacteria and fungi.<\/jats:p>","DOI":"10.3390\/ijerph16142557","type":"journal-article","created":{"date-parts":[[2019,7,18]],"date-time":"2019-07-18T03:11:42Z","timestamp":1563419502000},"page":"2557","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":20,"title":["The Study of an Ultraviolet Radiation Technique for Removal of the Indoor Air Volatile Organic Compounds and Bioaerosol"],"prefix":"10.3390","volume":"16","author":[{"given":"Chao-Yun","family":"Liu","sequence":"first","affiliation":[{"name":"Institute of Environmental Engineering and Management, National Taipei University of Technology, Taipei 10608, Taiwan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Chao-Heng","family":"Tseng","sequence":"additional","affiliation":[{"name":"Institute of Environmental Engineering and Management, National Taipei University of Technology, Taipei 10608, Taiwan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Huang-Chin","family":"Wang","sequence":"additional","affiliation":[{"name":"Union Professional Group of Architecture, Taipei 10608, Taiwan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Chuan-Fa","family":"Dai","sequence":"additional","affiliation":[{"name":"Institute of Environmental Engineering and Management, National Taipei University of Technology, Taipei 10608, Taiwan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yi-Hsuan","family":"Shih","sequence":"additional","affiliation":[{"name":"Institute of Environmental Engineering and Management, National Taipei University of Technology, Taipei 10608, Taiwan"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2019,7,17]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"101","DOI":"10.1007\/s100220100046","article-title":"The use of ultraviolet germicidal irradiation (UVGI) in disinfection of airborne bacteria","volume":"3","author":"Green","year":"2001","journal-title":"Environ.
